使用 Text 增加文本框大小 [英] Increase textbox size with Text

问题描述

我不知道如何谷歌这个，它总是想出我不想要的答案.所以，我有一个文本框，我想要它有一个设定的大小，但是如果文本大于大小，那么我希望文本框的大小随着文本的增加而增加.

I didn't know how to Google this, it always came up with answers I wasn't looking for. So, I have a textbox, I want it so that it has a set size BUT if the text is larger than the size then I want the textboxes size to increase with the Text.

令人困惑吗?我不太擅长解释这些东西.

Confusing Right? I'm not too good at explaining this stuff.

新部分:文本框预装了此文本，但提供的答案仅在输入时有效.我在文本框中找不到 onload，那现在怎么办?

New Part: The textbox comes preloaded with this text, but the answers provided only work as they are typing. I can't find onload on the textbox, so what now?

推荐答案

这对我有用:

也在窗口加载时运行它(此示例适用于 asp .net 页面):

Also run it on window load (this example is for an asp .net page):

<script type="text/javascript" language="JavaScript" src="../../javascript/Utility.js">
</script>

<script type="text/javascript" >
    window.onload = Init;

    function Init()
    {
      ResizeTextarea(document.getElementById("<%=tbDetails.ClientID%>"));
    }
</script>
